What kind of vesc, is the best for this remote ?

Or can i use this one https://www.aliexpress.com/item/Maytech-Dual-VESC-based-controller-electric-skateboard-longboard-dual-ESC-based-on-VESC-vedder-Pcb-BLDC/32948876329.html

Then the FIREFLY REMOTE makes no sensor for u. The Remote is specially made to receive specified data from the ESC (VESC compatible).

Dont choose the VESC for your remoteā€¦ choose the VESC for your board/motorsā€¦

Any VESC based ESC will work.

@Mich21050 It will workā€¦ but not live data. Thats what i told him in the post beforeā€¦ EDIT: Lol the post is missingā€¦ strange. Sorry

Now, this is starting to confuse me. I have this ESC https://www.ebay.com/itm/Dual-motors-longboard-skateboard-controller-with-remote-ESC-Substitute/302812941839?hash=item46810ece0f:m:mEjYlp9id5UtRAwhPmlchiw the belt one

But I can only find GND, W, V, U, 5V on the ESC. and what do you mean with live data, like I cant see how fast i am going??

Btw this is my second board i am building. But first controller :slight_smile:

2047

How? As far as I know this esc hasnā€™t got a pwm (ppm) input. @niel5046 you wonā€™t get live data, like speed and so on.

2048

Okay. My build is 2 belt motors. And what kind of vesc, do i need to buy to get live data :slight_smile:

2049

It doesnā€™t matter. Your esc just needs to be vesc based.

2050

Okay now i understand. I am just gonna buy this one https://www.aliexpress.com/item/Maytech-Dual-VESC-based-controller-electric-skateboard-longboard-dual-ESC-based-on-VESC-vedder-Pcb-BLDC/32948876329.html?spm=2114.search0104.3.84.4e7a7ac9HsTVcN&ws_ab_test=searchweb0_0,searchweb201602_6_10065_10068_319_10059_10884_317_10887_10696_321_322_10084_453_10083_454_10103_10618_10304_10307_10820_10821_537_10302_536,searchweb201603_70,ppcSwitch_0&algo_expid=7bb6c018-0fcd-4e51-b0b6-9e859e360fd1-13&algo_pvid=7bb6c018-0fcd-4e51-b0b6-9e859e360fd1 when i get the datasheet. :smile:

This one would work but itā€™s not really reliable.

2052

How do you know its not really reliable ?

2053

what do you guys think of my project so far? Its a work in progress that i hope can get even better with all of your thoughts

2054

?

How do you know that itā€™s not reliable

2055

Maytech vesc is know to cheap out in essential components, most probably will not run on FOC

I am sure it has been asked an answered, but I cant seem to find it in the thread - After building the remote. Is the throttle bar supposed to deflect to fill the entire bar (for throttle and brake)? If so, how do I calibrate that.? ffremote1

How do I get into the settings (holding the throttle full without the trigger does not work)?

Is there a wiki where we can start adding all the answers we find?

Thanks

2057

Jodel trigger kn start up the remote.

U ll find some settings to calibrate the throttle.

Short question which spring is recommended? Which springdimensions do you use

2059

15mm x 0.4mm is best (0.4-0.6 depends on how strong u want the feedback)

But in the Google list stands 20mm

2061

Yeah, for me is 15 mm betterā€¦ go for both. just a few cents.

Thanks @StefanMe ā€¦ That helped.
How do I get into the settings menu on firefly remote? Hold trigger while powering on remote.

For those in my situation: throttle does not reach Max - I opened up the remote.
And noticed that the spring was preventing the throttle movement to go max either direction. IMG_20190411_090228008%20-%20Copy

So I filed down lever that the spring attaches to. Then re-bent spring to make more clearance. I also filed the remote housing a little to allow the throttle wheel to move a little more forward and a little more back (just a tiny bit).

Then I opened up the code. Uncomment #define DEBUG

Then added this right after throttle variable is populated

#ifdef DEBUG

Serial.println(throttle);

#endif

Then plugged in the remote to the computer and opened up serial monitor. Then watch the serial output while moving the throttle. Then I filed down the previously mentioned pieces till I got 1000 on full throttle, and 0 on Full Brake.

ffremote_file_1

tags: throttle does not reach max, how do i enter the settings menu, firefly remote settings

2063

hmm no u donā€™t have toā€¦ just go into settings where u can calibrate the min, max and center value for the hall sensorā€¦

Hold the trigger on startup until the menu appears to join the settings menu
